After the introduction stage, Korean mobile game market is approaching to the growing stage leading mobile contents market. The environment for the mobile contents business is getting better by the expansion of the 3G mobile networks and the enhancement of the mobile devices. In this research, at a content level, not a service level, market success factors of mobile games and the differences by genres and their changes over time were investigated through the analysis of the real market data of mobile games launched by a Korean mobile carrier. The most important factors for market success, especially for the genres of RPG/Tycoon/Simulation and Shooting/Action/Arcade, were found to be the 'design' factor and its effect turned to be getting stronger as time goes by after the launch. Consumers' purchase rate was actually higher for the mobile games of popular genres or in relation with socially popular subject matters. Also 'design' and 'creativity' factors which are related to the quality of contents, have gotten more important over time. One of the most interesting results was that there existed a "blue ocean" genres like Sports/Racing/Leisure which had a steady demand but not many competing games. In the analysis of the 'convenience' factor, one interesting implication for mobile game producers was that there exists a trade off between the ease of initial adoption and the steady sales of a mobile game.

This increases the related cost, which makes the continued development of small and medium-sized game companies more difficult. Therefore, this study attempts to understand consumer values according to the type of mobile game marketing and to explore the factors that affect the switching intention of mobile games based on real users of mobile games. As a result of this study, it was found that the playfulness and economics of mobile game marketing have positive effect on the attitudes towards mobile game advertisements and attitudes towards mobile games, but the attractiveness of mobile game marketing using celebrities does not. It was found that attitudes towards mobile game advertisements and attitudes towards mobile games have an influence on the switching intention of mobile games. Through this, we intend to provide useful implications for small and medium game companies to seek effective marketing plans.

This study is conducted to explore the possibility of service convergence to promote mobile learning. This study has attempted to identify how mobile learning service is provided, which services among them are considered most popular, and which services are highly demanded by users. This study has also investigated the potential opportunities for service convergence of mobile service and e-learning. This research is then extended to examine the possibility of active convergence of common services in mobile services and e-learning. Important variables have been identified from related web pages of portal sites using social network analysis (SNA) and association rules. Due to the differences in number and type of variables on different web pages, SNA was used to deal with the difficulties of identifying the degree of complex connection. Association analysis has been used to identify association rules among variables. The study has revealed that most frequent services among common services of mobile services and e-learning were Games and SNS followed by Payment, Advertising, Mail, Event, Animation, Cloud, e-Book, Augmented Reality and Jobs. This study has also found that Search, News, GPS in mobile services were turned out to be very highly demanded while Simulation, Culture, Public Education were highly demanded in e-learning.

The traditional broadcasting system, which was operated by the mass media and the terrestrial broadcasters, is now transformed to the viewer-centered and bidirectional media through the convergence of internet and mobile. In terms of broadcasting environment, the function of the traditional TVs has been changed to the Smart TVs combined with an open platform which not only deliver visual contents, but also supply various applications and additional information linking the content providers and viewers. This ongoing broadcasting environmental change has made it possible for viewers to participate in the programs such as reality shows or sports events through SNS, texting or phone calls. Therefore, the purpose of this experiment is to present the ways to promote easier and more convenient viewer-participation in the programs by applying mobile messenger to existing broadcasting system in order to enhance the involvement of broadcasters and viewers of the programs and to diversify the roles of content providers and viewers in broadcasting.
